TIRE VALVE.

Application led May 10,

This invention relates to valves for pneumatic tires or the like andaims to provide certain improvements therein. y

The invention is particularly directed to a valve adapted for use onwheels of the disk typ-e. In this type of wheel, there being no spokes,pro lfon ist be made for gaining access fis the end of the tire valvefor inflation, deflation, and gauging, which operations are easilyaccomplished in the ordinary wood or wire wheel by reason of the spacesbetween the spokes which permit the pump coupling or gauge to be freelyapplied to the end of the valve.

According to the presentinventiony I provide a fitting which isapplicable for use in connection with wheels of the disk type, 'whichfitting is angular in form and which, in eilect, constitutes acontinuation of the valve, one end of the litting being connected withthe valve, and the other preferably projecting through the disk in adirection which is substantially parallel to the wheel axis. Preferably,this fitting is provided with .means for depressing the tire valve pinwhereby gauge readings can easily be taken by applying the gauge' to thefree end of the litting, and whereby the operation of deflating may beeasily accomplished. The invention includes certain other features ofimprovement which will be hereinafter moi/'p y fullyl described.

Referring to the drawings which illustrate the invention as applied to adisk wheel constructed of wood,

, Figure -1 isan elevation of the invention, the wheel being shown indiametrical section'. Fig. Zis an elevation at right angles to Fig." l1,certain parts-being broken away.` Fig. 3 is a sectional vi roug thevalve',1 -part of the wheel disk being shown in section. Fig; 4;' is aview similar to Fig. 3 showing the partsin dea'tin 'or gaugingposition.l

'Referring to the rawings, let A indicate the'wheel as a whole which isshown as comprisin ra' central web or disk B, the periphery of whlchhassecured to it, a metallic'rlm C.

The diskfB is shown as constructed oflamihated wood, and whil'eit isillustrated as dislaced somewhat toione side of-*the wheel, it,nevertheless, occupiesthe central portion of the4 wheel so that it mustbe recessed as shown at lD (Figs. 1 and 2) to receive-the tire valve E.Y

passing through a suitable hole in the demountable rim G and fixed rimC. It is desirable from the standpoint of appearance, and for otherconsiderations, that the exterior of the wheel shall be as continuous aspossible. For this reason, it is advisable to arrange the wheel so thatthe recess D is on the interior lof the wheel, or that side which facesthe car.

According to the present invention, I provide a fitting I-I whichpreferably is detachably secured to the valve E and which alsopreferably is 0f`right angled construction so that when secured to theradially arranged valve, its operative end I extends transversely to thedisk, or parallel Withthe axis of the wheel. The projecting end I isbest screwthreaded to receive the ordinary pump coupling, and theattaching end J is best provided with a union K for connecting itwiththe valve nipple L. The union shown comprises a swivel member M (seeFig. proy Vvided with a detachable-nut N held in place by a threadedsleeve O. This construction of union is not claimed herein since itforms the subject matter of a pending application iiled by me.

According to the preferred iformnof 'the present invention, I providemeans extendingy to the end I of the iitting by :which the pin l?` ofthe tirevalve (Figs. 3 and 4) may be depressed in vorder that th'e'valvemay be placed in communication with the fitting for purposes ofdeflation or gauging. The means f `I prefer to employcomprise apair ofmembers Q., R these members constitutin in effeet, a rod or pin leadingfrom the va 'vecpin 1s referably constructed as a 'pin shapedmem-- er,the lower end of which is best concaved p sli htly as. shown atv S toengage the tire va ve pin P and is best provided with a spring vpointedends of thetwo pin members `comprise in effect, wedging. surfaces by.means of pointed and which is adapted toena. reduced .-T, whichnormallyfholdsthe'pin Q in its. l

which,iwhenthe. extension U isjpressed in- .,jvardly, thefpin'membervQis p i wardly to open the tire valve. By forming the abutting endsofthe two pin members, symmetrically pointed, as shown, these membersmay turn in any direction without ai'ecting their operative connection.The head of the member' Q affords a suitable shoulder against which theupper portion ot' the spring T abuts whilethe lower end of the springbest bears against a detachable sleeve V which may be held in place bythe packing washer W of the fitting. This permits the pinmember Q to beeasily removed or replaced by removing the nut N. The pin member R isbest held in position by a screw-threaded sleeve X which bea-rs againsta shoulder Y formed between the body of the member and the reducedextension U.

The fitting H preferably has means for clamping it to a portion of thedisk l5, such means being shown as a fixed flange Z and a disk nut Z',the first bearing against the inner face of the web and the second beingadjusted on the exterior of' the wheely in order to clamp the fitting inplareon the disk.

Preferably, the recess D formed in the disk is enlarged as shown at Dand a slot D2 is best provided which passes throughthe disk B, the slotbeing elongated radially as best seen in Figs. 1 and 2.

In applying the fitting to the wheel, the

demountable rim G is first adjusted in place with the valve E projectinginwardly through the fixed rim C. The fitting is then applied from theinner side of the wheel and the coupling J screwed down to make a leakwtight joint between the fitting and the valve nipple. In so doing, theright angled' part of the'fit'ting may slide easily in the slot I)';This slot also provides sufficient room for apf plication of the fittingto valves of different degrees of projection through the rim. Vhcnadjusted in place, the flange Z being oi" greater diameter than thewidth of the slot D2, bears against 'the inner face of the recessedportion of the disk and the end vI of the fitting projects through thedisk outwardly to the exterior. The nut Z is then applied opened. Soalso, if it is desired to determine L the pressure in the tire, a gaugeof a standard type may be pressed on the end I of' th'e fitting, thegauge depressing the pin R. The

pin R is normally maintained in its extended position by the spring T,which, in forcing the pin member Q upwardly, moves the pin R outwardly.An ordinary valve cap may be applied to the end I of the'itting in orderto prevent any leakage if the tire valve fails to seat properly orbecomes injured. The fitting preferably does not maintain the tire valvein its depressed position, the latter remaining closed until the pin Ris pressed inwardly.

A While I have shown and described one form ot' the invention, it willbe understood that I do not wish to be limited thereto, as variouschanges may be made therein without departing from the spirit of theinvention. While the pin members Q and R 'are shown as separate members,it will be understood that these may be connected in any manner whichwill permit the movement otl the extremity of the pin R to betransmitted to the valve pin. be made if desired.

What I claim is The combination with a wheel having a disk, an elongatedslot through said disk, and a tire valve having an angled fittingpassing through said slot, said angled fitting having means for clampingsaid disk. said clamping means comprising a fixed disk on the' angledfitting and a screw-threaded disk adapted to engage a thread on theangled fitting and clamp the wheel disk between the two.

In witness whereof, I have hereunto signed my name.
